Bug Description

Binary package hint: xserver-xorg-video-intel

Thanks to the overlay fix video playing works fine under compiz with new Intel driver but after changin to console every xv player shows only a black or blue screen. The sound is working but there is no image. After some seconds, normally after closing the Video player, the laptop freezes completely that even the hardware mute button doesn't work anymore (led doesn't flash). Both problems happen without compiz too but it seems that it takes a little bit longer or another video start after changing to console to crash the system. If I don't start any video after mode change Laptop doesn't seem to freeze.
The freeze isn't duplicate of the Bug #127101, which often crashes my Laptop too, since desktop is still watchable (no gray rectangles) but maybe they are connected.
I hadn't this problem with i810 at least before trying new Intel driver.
I am using Sony TX2 laptop with i915 graphic card and current Gutsy.

Willi,
regarding the backtraces, 2 things could happen:
a) The backtrace matches the one I've posted. In that case it's not necessary you dupe it, unless there's some info I haven't provided.
a) The backtrace is different, meaning that it's not referring to the same problem. Check if the problem is already reported or alternatively file a new bug report.

In general having a backtrace is very useful in order to identify where the problem is and also to check if that's already reported.
Thanks for you interest.

Thanks to the overlay fix video playing works fine under compiz with new Intel driver but after suspend, which works fine, every xv player shows only a black or blue screen. The sound is working but there is no image. After some seconds, normally after closing the Video player, the laptop freezes completely that even the hardware mute button doesn't work anymore (led doesn't flash). Both problems happen without compiz too but it seems that it takes a little bit longer or another video start after suspend to crash the system. If I don't start any video after suspend Laptop doesn't seem to freeze (independent of compiz).
The freeze isn't similar to the Bug #127101, which often crashes my Laptop too, since it happens without switching video mode and the desktop is still watchable (no gray rectangles).
I hadn't this problem with i810 at least before trying new Intel driver.

Is there any possibility to get the Intel driver without the Overlay fix to check if they are connected?

The easiest way to confirm this issue is to run a video with Totem and then suspend. After resume video window is black and sound stops after some seconds or doesn't appear again. If I now close Totem PC freezes completly. This is independent of compiz and Totem since Vlc usage results in the same.

It has something to do with console change not with suspend. So the easiest way confirm the issue is to run a video with Totem (xv) and close it. Then switch to console and back. If you are lucky you got no gray rectangles (Bug # 127101) and come back to desktop. Now start another video with Totem, which should have a black video window, let it run for some seconds and then close it. System should freeze. Maybe you have to wait some seconds longer for video play if nothing happens.

I can confirm this bug. In gutsy, when i start watching a video in totem, switch to the console using ctrl-alt-f1 and back then the video is black. Then I closed totem and started it again. The video was still black. After some time the laptop froze, not even sysrq worked. I used xv as video output and "intel" as driver.

Another interesting point. After installing patched xserver-xorg-core from bug #127101 system doesn't freeze anymore but XV output is still black or blue after console change. In Most cases X crashes/restarts after such a change and video player exit. Sometimes X/Keyboard freezes but mouse is still moveable and video sound works normally like under bug #138094.

1. Open some video file in totem.
2. Switch to VT1. At this point I've seen the gray blocks hang from bug #127101, but I think now it only happens when video is being played.
3. Switch back to VT7. Video in totem is black.
4. Keep switching to VT1 and back to VT7 while the video is playing until system hangs.

Another interesting point is that I haven't this problem if I use an external monitor (VGA) and have LFP (LVDS) disabled with xrandr. There is another issue with dark video colors after switching to console and the video overlay is on top but xv still works. The dark video color problem could be fixed through closing video an reopening it with Totem but not the overlay on top issue. This needs an x restart.

latest git of intel driver fixes this issue for me it doesn t hang when trying to play the second or further videos , but I still can t switch to VT after I ve played video with xv. Segfault as in Bug#12451, similar backtrace

* 01_fix_compiz_video.diff:
- Bracket second clause in test for textured video to avoid
compiler warning and possibly incorrect testing.
* 04_fix_hw_restore.diff
- Only restore palette registers for pipes which are enabled, or
the system may hard-lock. (Initial patch by Bryce Harrington).
(Closes LP: #127101)
* 05_fix_xv_reset.diff
- Playing Xv video after switching modes once the Xv driver is
initialised causes a lockup, as the overlay regisers needre-programming. Ensure such a reset happens after a mode-switch.
